Extraction of Circular Target Applying Level Set Method
Zhou Chang-xiong · Journal of Suzhou Vocational University · 2010
Extracting a circular target is difficult in image segmentation.The paper puts forward a new level set method with information of regions.The method uses an external energy term with grayscale information of regions to drive the contour curve to the aim boundary.Compared with the model without regions information,the new method can extract a circular target better,and the outer and the inner boundary can be extracted at the same time.
